     "The Visualization Toolkit (VTK) is a C++ library for 3D computer graphics,
image processing and visualization.  It supports a wide variety of
visualization algorithms including: scalar, vector, tensor, texture, and
volumetric methods; and advanced modeling techniques such as: implicit
modeling, polygon reduction, mesh smoothing, cutting, contouring, and Delaunay
triangulation.  VTK has an extensive information visualization framework, has
a suite of 3D interaction widgets, supports parallel processing, and
integrates with various databases on GUI toolkits such as Qt and Tk.")

It's particularly good at processing large images, working with colour,
scientific analysis, and general research & development.

Compared to most image processing libraries VIPS needs little RAM and runs
quickly, especially on machines with more than one CPU core.  This is primarily
due to its architecture which automatically parallelises the image workflows.")

scientific image processing, segmentation, and registration.  Segmentation is
the process of identifying and classifying data found in a digitally sampled
representation.  Typically the sampled representation is an image acquired
from such medical instrumentation as CT or MRI scanners.  Registration is the
task of aligning or developing correspondences between data.  For example, in
the medical environment, a CT scan may be aligned with a MRI scan in order to
combine the information contained in both.")
